4 Alignment and Adjustments
4-2 AN17K*/AN17L*
CONFIDENTIAL
Signal: 1024 x 768 (68 kHz/85 Hz)
Display image: Don’t care
Contrast: Minimum
Brightness: Minimum
Limit: 26.0 kV ± 0.3 kV
Measure the high voltage level at the anode cap.
High voltage should be within the limit as above.
4-2-2 CENTER RASTER
Adjust SW401 so that the back raster comes to the
center when you apply basic mode for 17”.
4-2-3 Centering
Centering means to position the center point of
the display in the middle of the display area.
Horizontal size and position and vertical size and
position control the centering of the display.
Adjust the horizontal size and vertical size to their
optimal settings: 312 mm (H) x 234 mm (V).
Adjust the horizontal position and vertical
position to ≤ 5.0 mm of the center point of the
screen.
|A-B| ≤ 5.0 mm. |C-D| ≤ 5.0 mm.

* In Softjig window, “Geometry” has to be
selected for GD adjustment.
4-2-3 (a) HORIZONTAL SIZE ADJUSTMENT
CONDITIONS
Scanning frequency: 68 kHz/85 Hz

CONDITIONS
Scanning frequency: 68 kHz/85 Hz
Display image: Crosshatch pattern
Use control bar after selecting “H-POSITION” in
left menu to center the horizontal image on the
raster.
4-2-3 (d) VERTICAL POSITION ADJUSTMENT
CONDITIONS

Display image: Crosshatch pattern
Use control bar after selecting “V-POSITION” in
left menu to center the vertical image on the
raster.
4-2-4 Linearity
Linearity affects the symmetry of images as they
appear on the screen. Unless each row or column
of blocks in a crosshatch pattern is of equal size,
or within the tolerances shown in Tables 4-2 and
4-3, an image appears distorted, elongated or
squashed.
